DISABL-BLD ONSET

Disability/Blindness Onset Date. This data element identifies the onset date of disability as alleged by the claimant during the period in which the case is awaiting a medical determination, or if the case has been medically denied.

This date will be no earlier than the effective month of the SSI application unless information in the claimant’s medical file supports an earlier onset.
